he Cooper split tapered bearing is intended for the ‘fixed’
bearing position of shafts where there is both radial and axial
loading and our ‘G ’ cylindrical roller bearing is unsuitable.
T

t is constructed with two opposed rows of rollers to take
axial loading in either direction, and is intended to be used
with ‘expansion’ type bearings in all other positions on the
shaft.
Cooper split tapered roller bearings are generally mounted
in a ‘cartridge’ in a similar way to Cooper cylindrical roller
bearings. his is a spherically-machined inner housing that can
be fitted into a number of types of outer housing.
T
T
he spherical seat between the cartridge and the outer
housing accommodates misalignment between the shaft and
mounting structure.
T
T
he cartridge also houses the seals. his ensures that the seals
are maintained concentric to the shaft, even if there is significant
misalignment of the shaft relative to the outer housing.
Tapered bearing in cartridge
Outer Housings
As the cartridge spherical seat diameters are common to the
seats for Cooper cylindrical bearings, the bearing and cartridge
unit can be fitted in a wide variety of existing housing designs.
However, the two types most commonly used are the
pedestal (or ‘pillow block’) and flange.
A
T
T
Cartridges for tapered bearings are fitted with a hole
in communication with the outer race, for fitment of a
temperature element, as standard. he standard hole position
is in the end face of the cartridge. he proximity of this hole
to the shaft means that if the temperature element is of the
headed type, generally it will need to have a cranked probe.
lternative hole positions are possible, including radial holes
requiring additional holes in the outer housing.

Bulkhead sealing
It is often found economical to combine a bearing and
bulkhead seal into one unit. This reduces the number of
individual units required, and prevents problems with shaft
eccentricity sometimes encountered at the bulkhead seal when
it is separated from the bearing.
Generally, a specially adapted flange mounting is used and the
bearing is fitted with SRSRP seals (see page 6). Generally, the
flange incorporates additional sealing to the cartridge seating,
and may include sealing on the mounting face (‘backface’).
Where the shaft surface speed is too high for standard
SRSRP seals, an alternative high speed version is available, or
alternative seal types can be used if a moderate leakage of
water is permitted through the bearing in an emergency.

Bearing Selection
Life calculation with multiple load conditions
Bearing ratings for dynamic radial capacity (Cr) and static radial
capacity (Cor) shown in this leaflet are in accordance with ISO
281-1990 and ISO 76-1987 respectively.
Where varying loads are experienced in operation, using the
maximum load condition may lead to an unrealistically low
calculated life. For n load conditions constituting the full load
cycle (at constant speed), an overall dynamic equivalent load
may be calculated as follows:
i=n
0.3
P=
Pi(10/3)pi
i=1
Radial and axial loads must be considered together as
combined ‘equivalent loads’, as explained below. Generally,
maximum instantaneous loading is governed by housing
strength rather than bearing static capacity.
Dynamic rating
Expected bearing life is calculated by the following equation:
L10 = [Cr/(P x fd)](10/3)
where:
L10
= expected life of 90% of similar bearings
under similar operating conditions
Cr
= radial dynamic rating
P
= equivalent dynamic load
fd
= dynamic or service factor, generally from
1 for steady loading to 3.5 for heavy shock,
reciprocation or vibration
The dynamic equivalent load is calculated as follows:
when Fa/Fr ≤e : P = Fr + Y1Fa
when Fa/Fr >e : P = 0.67Fr + Y2Fa
where:
Fr
= applied radial load
Fa
= applied axial load
and calculation factors Y1, Y2 and e are given in the product
data tables.
[∑
where:
Pi
pi
]
= dynamic equivalent load under load
condition i
= proportion of time load condition i is
applicable
Where the load is continuously variable it may be broken
down into a discrete approximation to the actual load cycle.
Minimum loading
In order to avoid excessive skidding of the rollers, sufficient
loading must be applied to the bearing, as follows:
P ≥ 0.01Cr
2
Static rating
The static load rating is defined as the load at which a contact
stress of 4GPa occurs at the centre of the most heavily
loaded contact, and at which a permanent deformation of
0.0001 times the roller diameter is sustained at the location
of the contact. This has been found to not cause significant
deterioration in bearing performance under typical operating
conditions.
The suitability of a bearing for sustaining a specified static (or
instantaneous maximum) load is determined as follows:
Cor ≥ So x Po
where:
Cor = static radial capacity
So
= static safety factor
Po
= Fr + YoFa where calculation factor Yo is
given in the product data tables.
Standard shaft design
Temperature Characteristics
Standard bearings can operate at between -20°C and 100°C.
Operation outside this range is possible but may require
special treatment of bearings parts – please contact our
technical department.
The difference in temperature between the shaft and housing
3 should not exceed 40°C.
Standard shaft design with ATL seals
(where applicable)
Mounting Arrangements
General arrangements
In order to provide accurate and positive location of the
inner race on the shaft, these bearings are generally mounted
on a recessed journal, and the standard cartridges and seals
are designed to suit this arrangement. As the bearings are
completely split to the shaft, there is no need to provide
separate collars to create this recess – it can be machined
directly into a solid shaft. Also, there is no need to design the
surrounding parts to allow for axial assembly of the bearing
and it can be fitted between integral shaft flanges, cranks,
mounted parts and assemblies etc.
Usually, the shaft is carried through the end of the cartridge
at the diameter of the journal abutment, with the seals
operating on this larger diameter. If aluminium triple labyrinth
(ATL) seals are to be used, on some sizes the diameter of the
cartridge end bore would be excessive with this arrangement,
so the shaft has only narrow shoulders abutting the inner race,
with the seals operating on a diameter equal to the journal
diameter.
Shaft design for ATL seals
where standard not applicable
If the journal and the portions of the shaft under the seals
are required to be of the same diameter and integral abutting
shoulders are not possible, alternatives are to use spirally
wound retaining rings mounted in grooves in the shaft, or
special split location collars (usually requiring special cartridges
to accommodate them). It may be possible to locate the
inner race on the shaft using only the clamping effort provided
by the inner race clamping rings, without auxiliary location
features, but this should only be done in consultation with
Cooper technical department.

All arrangements not conforming to the standard designs
illustrated in the product data tables will require confirmation
of dimensions and part codes for the cartridges and seals.
Alternative abutment diameters can be accommodated using
alternative seals and housing end bores. If larger shaft fillet
radii are required, we can supply bearings with extra large
chamfers to the inner race bores.
Shaft tolerance
Shaft tolerances are as illustrated opposite. The tolerance on
roundness and parallelism of the journal is IT6.

A tolerance of h9 is applicable to the seal seating area even
when it is the same nominal diameter as the journal.

Sealing
Standard Cooper housed tapered bearing units incorporate
a cartridge with spherical seating, which maintains the seals
concentric with the shaft under misaligned conditions.
Compared to units where the misalignment is taken up
between the bearing and outside housing, closer running
clearances (in non-contact seals) or more even seal pressure
can be maintained.
Grease groove (LAB)
Supplied as standard. Suitable for high or slow speed
operations. Particularly successful on marine applications
when conditions are clean and dry.
Cooper offer a wide range of seals, together suitable for most
environments. Some of the more common options are shown
below. Further types, or combinations of seals, are possible.
Different cartridges are required depending upon seal type.
Felt, high temperature packing and single lip (SRS) seals all use
a common cartridge.
If felt seal are specified, these are supplied with the cartridge
(although they can still be ordered separately). Other
seal types must be ordered separately (i.e. they are not
automatically supplied with the cartridge).
Maximum operating speeds of the various types of seals
are specified in dn(mm). To calculate the speed in dn(mm)
multiply the shaft speed (in rpm) by the diameter of the seal
seating area (in mm).

Cooper tapered bearings and housings are designed for grease
lubrication. Grease is easier to retain in the housing than
oil, offering reduced lubricant loss and improved sealing. It
also offers better protection against corrosion to the rolling
surfaces.

BSP fittings may be used, but care must be taken to avoid
blocking off the lubricant cross-drilling as these fittings
generally screw in further than NPT fittings.
Greases of NLGI No.2 designation are recommended for
most applications. For centrally pumped systems a No.1
grease may be used for increased ‘pumpability’.
Greases with extreme pressure (EP) additives are
recommended.
Grease with a lithium complex thickener is usually used for
normal applications operating at temperatures between
0°C and 80°C. When water resistance is required a grease
with aluminium complex thickener can be used. Aluminium
complex greases are not compatible with some other types
of grease. The bearing must therefore be solvent cleaned of
other greases before adding an aluminium complex based
grease.
For extreme temperatures, speeds and loads always obtain a
lubricant recommendation from our technical department.
Selection of base oil viscosity
In order for the bearing to have a long service life the grease
selected for bearing lubrication must have a base oil of
sufficiently high viscosity to adequately separate the rolling
elements and race parts under operating conditions.
The charts in Figure 2 show the recommended operating
ranges for three common oil viscosities, for bearings under
normal loading (up to Cr/10).
To use these charts, find the ‘geometry factor’ for the bearing
from the table below and multiply this by the bearing speed in
thousands of rpm to obtain the velocity factor.
D
haft iameter
d (mm)
Lubrication points are tapped 1/8”NPT and fitted with nipples
for grease lubrication as standard. Grease nipples may be
removed and replaced with other fittings or pipes. Pipework
must be flexible to allow the swivel cartridge to function
correctly.
11
etr
For example, if a 100mm bearing is to be run at 1200rpm:
The geometry factor is 96 from the table
Velocity factor = 96 x (1200/1000) = 115.2
To determine the suitability of one of these oils, draw a
vertical line from the horizontal axis at the calculated velocity
factor, and draw a horizontal line from the vertical axis at the
operating temperature.
If the lines intersect in the shaded area the viscosity of oil is
suitable. If the lines intersect above the shaded area a higher
viscosity oil is required. If the lines intersect below the shaded
area the bearing may operate satisfactorily but it is suggested
that a grease with a lower viscosity base oil is used.
The use of these charts is subject to the operating conditions
being within the recommended ranges for the lubricant as
specified by the lubricant manufacturer.
For conditions not covered by these charts please contact our
technical department.
Note that the lubrication film thickness is not particularly
sensitive to load, so for heavier loading the lubricant selection
as provided by these charts is usually sufficient provided
that the lines drawn on the chart as explained above do not
intersect at the upper edge of the shaded area.

Grease quantity for initial lubrication
Routine Greasing
The quantity of grease required on initial lubrication is
dependent upon operating speed and temperature.
Relubricate the bearing weekly or every 150 hours of
operation.
Sizes up to and including 120mm: Use 2ml of fresh grease.
Sizes over 120mm: Use 4ml of fresh grease.
Note that 2ml is approximately 1 shot from a conventional
side-lever grease gun.
If the operating temperature is below 80°C the quantity of
grease may be determined directly according to the bearing
reference and operating speed from the table below. If the
operating temperature is above 80°C a 25% pack of grease
should be used regardless of operating speed (refer to the
right hand column of the table).
Automatic lubrication systems should be metered to deliver
grease at an average rate equivalent to the routine greasing
periods and quantities specified.
With a ‘full pack’ of grease the space within the housing (i.e.
surrounding the bearing components) in the assembled unit is
completely filled with grease.
The table assumes normal density grease (about 0.85 g/cm ).
3
If it can be done safely, the bearing should be re-greased as it
rotates to help distribute the grease.
Do not mix different types of grease in the bearing. Excessive
quantities of lubricant should not be used, particularly at
high speeds, as this may result in excessive churning and
overheating.

Frequency Data
Bearing frequency data are included in this document for two
purposes:
•
•
to allow machine designers to check excitation frequencies
against resonant frequencies in the machine,
to allow correct input into condition monitoring
equipment that uses these data.
A roller bearing will excite vibrations at certain frequencies
related to the number, size and pitch circle diameter of the
rollers. To some extent this excitation is present even with
new bearings in perfect condition, as the load is carried on
discrete, elastic, rolling elements which are constantly changing
in angular position.
The table at the top of the page opposite indicates the
frequencies of bearing parts per shaft revolution, which can be
used to calculate excitation frequencies directly by multiplying
the tabulated frequencies by the shaft speed.
The frequencies listed are explained as follows:
‘Cage’ – the frequency at which a point on the cage enters and
leaves the loaded zone of the bearing
‘Roller’ – the frequency at which a point on a given roller
passes into contact with either the inner or outer race
‘Outer’ – the frequency at which a point on the outer race
comes into contact with successive rollers
‘Inner’ – the frequency at which a point on the inner race
comes into contact with successive rollers
The table also lists the pitch circle diameters, number of rollers
and contact angle for use with condition monitoring equipment
that accepts this information.
